At the country's oldest glassworks, which have been in operation since 1817, you can watch the glassmakers at work (free of charge). From a platform, visitors look down on the ovens and can even blow a ball of glass to take home as a souvenir (for a fee). A museum (collection of pieces from the 18C and 19C, the company's archives), shop, children's toys and a lakeside café round off the visit.
